Ive lurked here for a while but finally have something to post!
I need help identifying this coin,
Constantine I AE3 Cyzicus
CONSTAN-TINVS AVG, Laureate head right / PROVIDEN-TIAE CAESS, campgate, 2 turrets, 6 layers, star above, no doors. Mintmark SMKA dot.
The reverse should say Providen-tiae avgg not caess
In my opinion could be a mule with a constantine ii or constantius reverse. Any help with which reverse or if youve seen a similar coin before would be much appreciated!
